Fact is that with TB17 tabs are in the title bar that s why it looks that way. Default theme also truncates the upper border. For the moment I didn t have so much time to find some better solution for Windows XP users. I ll need to see how to force my theme to display like with TB16 but when you use TB17 or higher version. I m also not so satisfied how it looks under XP with TB17 installed. I prefer how it was before. There will be need to wait a bit to see what I can do. Right now I don t have the possibility to work on it.
